Specification of Letters Patent.

Patented Aug. 18, 1908.

Application filed. July 10, 1907. Serial No. 383,067.

To all whom it may concern:

Be it known that we, FREDERICK C. MIL- LER and Orro BUTZKE, citizens of the United States, residing at Springfield, in the county of Sangamon and State of Illinois,-

' car motors, but obviously may be embodied in motors for other uses, without departure from our invention.

The purposes of our invention are to provide a six wheel truck equipped with three axles all connected to be driven by a single wheelof a prime mover mounted on the platform of the motor, said truck comprising two members viz: a main truck and a pony truck having a swivel connection with each other, and the main truck having a swivel connection with the platform; so that all of the wheels may readily adapt themselves to the curves or the inequalities of the track on which they run; and thereby attain the best adhesion of the wheels on the rails, to provide clutch mechanism controlling the direction of the run of the motor so that the motor may be caused to run either forward or backward at pleasure; to provide a roller bearing adapted to facilitate the oscillation of the pony truck; to provide simple and effective means for connecting the platform with the trucks; to provide simple and effective means for controlling the run of the chain driving the axle of. the pony truck; and to provide simple and effective means for connecting the axle boxes with the truckframes.

With these ends in view our invention consists in the novel features of construction and combinations of parts shown in the annexed drawings to which reference is hereby made, and hereinafter particularly described and finally recited in the claims.

Referring to the drawings in which similar reference letters and characters designate like parts in the several views; Figure 1 is a side elevation of the complete apparatus; Fig. 2 is a top plan of the apparatus; part of the platform being shown as broken away, to expose the parts below the platform; Fig. 3 is an enlarged vertical transverse section on the line 3, 3, of Fig. 2; Fig. 4 is an enlarged partial vertical transverse section on the line 4, 4, of Fig. 2; Fig. 5 is an enlarged partial vertical section through the platform; and shows in elevation the chain guides and the means for supporting same; Fig. 6 is an enlarged partial vertical longitudinal section on the line 6, 6, of Fig. 2, Fig. 7 is an enlarged partial vertical section on the line 7, 7, of Fig. 2, and Fig. 8 is an enlarged detached isometric projection of one of the axle boxes.

The main frame A consists of a single channel bar bent to conform to the platform and having its ends secured together by an angle plate a; the floor or platform B is a single metal plate, preferably boiler plate, riveted or otherwise firmly secured on the frame A. The truck frames consist of two parts, viz.; a main truck and a pony truck having a pivotal connection with the main part, as hereinafter more fully described. The main part of the truck-frame com rises side bars D of channel iron of suita le dimension, connected by a cross bar D. The cross bar D passes through a stirru d (Fig. 7) secured on the under side of the datform B (Fig. 7). A washer (2 lies on top 0 the bar D; a bolt (1 extends through a hole in the cross bar D and through a hole in the stirrup d and has a nut d and a pin 61 securing the bolt in place and the cross bar D oscillates on the bolt. The pony-truck frame comprises a channel bar E bent substantially as shown in Figs. 1 and 2. A block E fits in the angle formed by the bent members of the bar E,and has flanges e fitting on the bar E and reventing vertical displacement of the bloc r. A bolt E extends through the bar E and the block E and secures the block on the bar. A plate F of suitable dimensions extends across and is secured on the under side of the latform and supports the block E. A bo t E extends through the platform B, the block E and the plate F and connects the frame E with the platform B and the plate F.

The axle boxes of the main truck-frame and the ony truck-frame are identical in construction. One of the boxes and the means for connecting same with the truckframe are clearly shown in Figs. 6 and 8. The box proper is a trough shaped structure G having a hinged ravitating door Gr communicatmg with t e interior of the box. The box G is secured on the bar E, or the bar .D as the case may be, by strap bolts Gr fitting 1n grooves gin the walls of the box G and secured by nuts g Brasses G3 of the sprocket wheel).

the under side of the latform support rollers.

H which turn free y in bearings on the brackets and. the rollers travel .upon a sege mental track H secured on the bar E. The axles K K and K and the wheels K are of the usual construction and the wheels are secured on the axle.

The prime mover C may be a steam engine, or gasolene engine, or other rime mover of suitable construction provided with a suitably located shaft C on which is secured the main drive wheel C (in this case a The sprocket wheel C, M and M and M have flaring flanges as shown. The sprocket wheel M is in line with the wheel C and turns on the axle K. The wheel M has a circumferential groove m accommodating the fork'm of the ship er lever M. The lever M oscillates on a ho t m and is provided with a latch m engaging in the notches of a quadrant M to control the movement of the lever M in the usual well known manner. A sleeve M is secured on the axle K and has a circumferential flange m A ring m fits around the sleeve M; A set screw m connects the ring with the sleeve and secures the sleeve on the. axle. A

sprocket wheel M turnable on the sleeve M,

is kept in place by the flange m and the ring m and has .an inte ral clutch member m coacting with the c utch. member m of the wheel M. A sprocket wheel M is fixed on the axle K and has. an integral clutch member m co-acting with the clutch member m of the wheel M. Sprocket wheels .M and M, having flaring flanges, are secured on the axles K and K respectively, in line with each other. Sprocket wheels M and M. are secured on the axle K inv linev with the sprocket wheels M and M? respectively. A sprocket chain m connects t.e wheels M and M. A crossed sprocket chain 'In connects the wheels M and M chain in connects the wheels M and M and a s rocket chain M connects the main drive w eel C with the sprocket wheel M. A bracket P secured on the under side of the platform B supports vertical shafts P. pools P turn on the shafts P. Collars p on the shafts P revent longitudinal movement of the spoo s on the shafts. The shafts P may be of any approvedconstruction; we prefer however to use shafts in the form of long bolts, passingthrough the.

platform B; and having heads 19', supporting connect; the wheels A sprocket block E and have intermediate parts 6 parallel to the sides of the platform and uponwhich the axle boxes are secured and beyond the intermediate parts the members converge and form paralle partse which are secured together by rivets 0 orequivalent securing devices. Holes 6 extendthrough the. part 6 and accommodate a link 6 for connecting themachine with-the cars. Curved bumper bars E are secured onthemembers E respec tively, and bumper lates E ofsuitable con:

struction aresecure on or near the lower end of the bars E. A draw bar B and bumper barsB of suitable construction are secured on the platform B. Bumper blocks B are secured on the bars B For convenience in. reciting in the claim the elements of the mechanism we hereby dese ignate the axles K, K and K asthe first second and third axles respectively;

and the sprocket Wheel C as the main drive sprocket wheel; the sprocket wheelM.

as the first, (driven) sprocket wheel; the

sprocket wheelM asthe second sprocket wheel; the sprocket wheel M as the third sprocket wheel; the sprocket wheel-M1 as the fourth sprocket wheel; the sprocket wheel M as, the fifth sprocket (wheel and.

the s rocket WheelMYasthe sixt sprocket whee and the sprocket wheel M as. the

.seventh, sprocket wheel.

In the drawings atstraight chain is shownconnecting the sprocket .wheels M and M and a crossedchain is shownconnecting thewheels M?" and M 9. The-crossed chain may however be used: toconnect the wheels M and M and the strai ht chainmay beused to 6 and M within the sco e of this invention.

n practicaluse of; the machine, the prime mover. O being in motion; the chain m run-- ning on. the sprocket wheels 0 and M, will. drive the wheel M; and the clutch member of.

the chain/m running on the wheels M and- M willdrive the axle K; tocause the ma-v chine to travel forward. To cause reverse travel of the machineit is only necessary to move the shipper lever M, to slidethe wheel.

into engagement with. the wheel M; whereupon the crossed chain m traveling onithe M out of engagement with thewheelM? and..

wheels M and M will cause the machine to travel rearward. In oing around curves the pony truck-frame wil turn on its swivel E to adapt the wheels to the track. It will be observed that the axles K, K, and K all have direct connection by means of the sprocket chains m", m, and m running on the sprocket wheels M M M M M and M hence the adhesion of all the wheels is constantly effective in propelling the machine. Stay-chains S connected with the truck frames and the "platform prevent excessive lateral movement of the truck frames.
